A new approach to kinetic energy flux at the different frequencies above the IRIS Bright Points
Rayhane Sadeghi, Ehsan Tavabi
Various bright structures abound in the chromosphere playing an essential role in the dynamics and evolution therein. Tentatively identifying the wave characteristics in the outer…
Dynamics of Explosive Events by Interface Region Imaging Spectrograph
E. Tavabi, S. Zeighami, M. Heydari
In this research, we investigate Explosive Events (EEs) in the off-limb solar atmosphere, with simultaneous observations from the Si IV, Mg II k, and slit-jaw images (SJI) of the I…
Polar regions activity and the prediction of the height of the solar cycle 25
S. Koutchmy, B. Filippov, E. Tavabi +2
The forthcoming solar cycle (SC) 25 was beleived to be rather low when using the sunspot number (SN) as a measurement of the level of activity. The most popular prediction was made…
Chromospheric peculiar off-limb dynamical events from IRIS observations
E. Tavabi, S. Koutchmy
To study motions and oscillations in the solar chromosphere and at the transition region (TR) level we analyze some extreme Doppler shifts observed off-limb with the Interface Regi…
Polar Coronal Plumes as Tornado-Like Jets
E. Tavabi, S. Koutchmy, L. Golub
We examine the dynamical behavior of white light polar plume structures in the inner corona that are observed from the ground during total solar eclipses, based on their EUV hot an…
Observation of galactic cosmic ray spallation events from the SoHO mission 20-Year operation of LASCO
S. Koutchmy, E. Tavabi, O. Urtado
A shower of secondary Cosmic Ray (CR) particles is produced at high altitudes in the Earth's atmosphere, so the primordial Galactic Cosmic Rays (GCRs) are never directly measured o…
